Problem in Conversion of PPTX to ODP in Java when Slide Has a Background Color

Good morning, I have a problem converting pptx files to odp. The problem occurs with slides that have a colored background. The background color is not reproduced in the file converted to odp. Can you tell me what the problem is or if I need to set something before the save operation? I attach the example file and the produced result. The version, for java, of aspose I’m using is 22.12

@L1b3r0,
Thank you for contacting support.

I reproduced the problem you described when converting the attached PPTX file to an ODP document using Aspose.Slides for Java 22.12, and we apologize for any inconvenience caused, but the problem goes away when using version 24.3. output.zip (5.3 KB)

We recommend that you use the latest version of Aspose.Slides for Java.
